FASTENING-INSERTING MACHINE Original Filed April 27, 1936 6 Sheets-Sheet 6 QZZW 1: W 1- Patented June 13, 1939 UNITED STATES PATENT OFFICE FASTENING-INSERTING MACHINE Jersey Application April 27, 1936, Serial No. 76,577 Renewed July 15, 1938- 125 Claims.

This invention relates to machines for inserting fastenings, it being especially applicable to the attachment of heels to shoes by the use of fastenings formed from strings of material, an

instance of which type of fastening is disclosed in Letters Patent of the United States No. 1,729,- 169, La Chapelle, September 24, 1929.

In the heeling of shoes, the non-metallic fiber disclosed in the above-identified patent has many advantages. If the fastenings penetrate the heel-seat, they will not injure the foot of the wearer nor, if they are acted upon by perspiration, affect the shoe-material. When a heel is worn, they will not mar floors or produce sparks by which explosions might be caused. The holding power of such fastenings is great, and many of the difficulties encountered in feeding loose fastenings are avoided. The invention has as an object, the provision of an efficient and relative- 1y simple machine by which fiber or like fastenings may be formed from strings of material, the

work pricked to receive said fastenings, which are then inserted to complete an attaching operation. The work may involve, for example, the attachment of heel-bases to shoes, the securing of lifts to previously attached bases or the simultaneous attachment of bases and lifts. Herein, the invention is described in connection with the insertion of fastenings for securing rubber lifts to previously attached bases. More particularly, the invention involves the structure of both the inserting die with its heel-holder and the co-opcrating pricking and driving or inserting assembly and the facilitating of changes of these elements to give different inserting designs; the manner of actuating the transferring device or loader by which fastenings are severed from strings of material supplied by a feeder and delivered to the die for insertion; the control of the devices whereby the work is successively pricked and the fastenings driven into the pricked openings, this control including the insertion of fastenings of different lengths in the same piece of 45 work; the production of an uninterrupted operating cycle, occurring in two stages; the supply to the fastenings of a liquid to increase their hold upon the work; and the feeding of strings for the production of the fastenings, this including the 50 supplying of fastenings of different lengths and the limiting of delivery to but one stage of the operating cycle.

The principal supporting and actuating elements of the apparatus may be as in Letters Patent of the United States No. 446,885, Pope, February 24, 1891, this patent disclosing the wellknown lightning heeler. Near the central portion of a frame ID a die-block D is mounted her izontally, and at opposite sides of this block rods l2, I2 reciprocate vertically. Bridged across the upper extremities of the side-rods is a top-girt or bar l8 by which are supported vertical drivers 22 movable into and out of registering passages 24 in the die-block. These drivers and passages are disposed in accordance with a particular inserting design, the character of which depends upon the work to be done. The side-rods are secured at their lower ends in cross-head 25 guided for vertical movement in the frame, and reciprocated through an eccentric rod 26 from an eccentric 28 upon a horizontal driving shaft 30. Power is applied to the shaft by a pulley 32 through a clutch 34, this clutch being controlled by a handlever 36 which actuates a lever 38 (Fig. 4) to trip the clutch and cause the machine to perform a single operating cycle. Upon a cross-head 40 movable vertically in the frame I0 is a work-supporting jack 42 arranged to slide horizontally upon the cross-head from an outer position, in which the work is applied, to an inner fasteninginserting position beneath the die-block D. In

the latter relation, it is located by an adjustable back-stop 44. To apply preliminary or measuring pressure to the work by forcing it against the under side of the die-block as an abutment, the cross-head 40 is supported upon a second vertically movable cross-head 45 by screw mechanism 46, which may be rotated to raise the lever. and jack by connections 48 to a treadle 50. Final clamping pressure is created by contacting cams 52, 52 rotatable upon the cross-head 45 and a cross-bar 53 of the frame by connections 54 to the side-rods I2. This final pressure is applied during the beginning of the power-cycle of the apparatus.

Taking up the portions of the machine with which our invention is especially concerned, the die D is best shown in Figs. 5 and 7. It has a central body-portion 60 received in opposite ways 62, 62 in the frame (Fig. 1) and normally retained in operating position by pivoted latches 64, 64. Secured to the body-portion 60 by screws 66 is an upper plate 68 and a lower plate I0. Through these plates are vertically alined portions of the passages 24, there being an intermediate space I2 in the body-portion. Depending from the under side of the plate I and surrounding the lower portions of the passages 24 are frusto-conical projections 13. These are preferably of such a length, that, when pressed into the yieldable material of a lift, their ends will lie close to its layer of reinforcing material. They thus furnish guides for the flexible fastenings, which are prevented from being defiected laterally from the pricked openings. Further, they may be arranged to enter thefasteningreceiving depressions which are formed in many rubber lifts and correctly register said lifts for the fastening-inserting operation. From the lower plate rise guide-tubes I6, these passing through openings in the lower portion of the body 60 and terminating at the space I2. I The upper plate 68 is extended rearwardly at 18 to furnish a fastening-shearing portion, in'which are openings 80 repeating the design of the passages 24. Into these openings project sections 82 of flexible tubes through which strings f of fastening-material are delivered. This material is preferably of fiber, as that disclosed in Letters Patent of the United States No. 1,729,169, La Chapelle, September 24, 1929.

To sever fastenings from the strings of material dependingthrough the openings 86 and supplied by a feeder F, to be hereinafter more particularly described, and to transfer the cut pieces into registration with the passages 24, a loader-block 84 is movable in the space 12. This block is provided with Vertical passages86 arranged in the same design as the passages 24 and the openings 80. In its extreme positions, its passages are first alined with the openings 8i! and then with the passages 24. In the former position, the strings are fed into the block-passages to such an extent as will give fastenings of the desired length. Then, as the block travels forward, the meeting faces of said block and the plate 18 co-operate'to shear off the ends of the strings to produce'a gang of discrete fastening s.

Primarily, movement of the block is effected through power furnished by a cam-groove 90 (Fig- 2) formed in the inner face of a gear 92 fast on a shaft 94 journaled in the lower portion of the frame parallel to the shaft 3E! and driven therefromthrough a pinion 96'meshing with the gear. A lever 98 fulcrumed upon the frame carries a roll I00 lying in the groove SI]. This lever at itsinner extremity is joined by a rod I02 extending vertically at the rear of the right-hand side-rod I2 (Fig; 4) to a slide I414 guided for vertical movement in the frame near the dieblock (Fig. 3). A link I06 connects the slide to the horizontal arm IIl'Iof a bell-crank-lever I08 oscillating about a spindle H0 fixed horizontally across the, rear of the frame. A substantially vertical arm H2 of the bell-crank-lever I08 has at its upperend a longitudinal slot I I4. A block I I6 is adjustable along the slot by opposite screws H8, H8, and a link I20 unites the block H6 with the loader-block 84. In the rearward position of the loader-block, the arm H2 is so inclined, that changing the position of the block H6 by setting the screws H8 will alter the horizontal relation of the loader-block-passages to the plate-openings 8B. Ihus, correct registration may be obtained. At the opposite extremity of movement of the loader-block, the lever-block I I6 is so located that its travel in the slot H4 in the arm IIZ is'about a center which coincides with the pivotal axis of the connection between the link I20 and the loader-block. Therefore, movement of the lever-block will have no effect upon the loader-block. Registration between the loader-block-passages 86 and the die-blockpassages 24 may be attained by varying the connections between the cam-roll I00 and the loader-block. For this purpose, there is shown a turnbuckle I2I (Fig. 4)- included in the connecting rod I02. As the rod is shortened or length.- ened, the loader-block is correspondingly shifted. By these independent adjustments, the loaderblock-passages may be accurately alined with both the openings 80 and the passages 24. To

more exactly insure that, upon their descent, the drivers will find the loader-block-passages properly positioned to receive them, a stop-screw I25 may pass through the front wall of the diebody I50 (Fig. 7). To avoid injury to the parts when the loader-block strikes the stop, because of excessive movement by its actuating means, and to maintain said block firmly against the stop during the action of the drivers, the lever IE8 is sectional, the arms IIE'I and H2 being mounted for relative movement on the spindle II Ii. To an upward projection from the outer end of the arm I01, a rod I29is articulated, it passing vertically through an opening in a block I3I pivotedupon a rearward projection from the arm H2. At the upper side, a shoulder on the rod is normally held against the block by a spring I 33, this spring surrounding the rod be tween the under side of the block and nuts I I threaded on the lower extremity of said rod. The elements may be so related that when the loader-block 84 engages the stop I25, movement of the arm 'I I2 will continue through a small angle, the spring I33 yielding and offering a resistance determined by the adjustment of the nuts I35. Any positive, harmful pressure of the block against the stop will thus be eliminated, and lost motion in the connections will be taken up. Perfect registration between the loaderblock-passages and the die-block-passages may therefore be made certain, and Vibration of the loader-block checked. Since, at the opposite extreme of travel, there is no stop for the loaderblock, engagement between the rod-shoulder and the block I3I produces positive movement. Something may occur to interfere with the movement of the loader-block. This may be due to the breaking of one or more drivers, broken pieces lying in both the passages 24 and 85. To prevent this from damaging the machine, a frangible element may be included in the connections between the cam-groove 99 and the loader-block. Herein, this is shown as a pin I2! (Fig. 4) joining telescoping sections of the rod I02. ,This pin is of some relatively soft metal, as'brass, and will be sheared off without injury to the other elements if the loader-block meets undue resistance.

The shearing of the plural strings of fasteningmaterial calls for the application of a greater force than can be supplied. readily by the connection just described. We therefore provide secondary or auxiliary means for moving the block during the severing period. A collar I22 (Fig. 1) is clamped to the left-hand side-rod I2 and is joined by a link I23 to the forward end of a bell-crank-lever i2 8 arranged to oscillate about the spindle H5. An upwardly extending arm I 25 of the lever I24 is united by a link I28 to one arm of a bell-crank-lever 39 fulcrumed at the left of the frame upon a spindle I32 (Fig. A second arm of the lever I35 carries a roll I34, and this, just as the block 84 leaves its fastening-receiving position beneath the openings 85, contacts with a projection I 3.5 at the rear of the loader-block. This applied intermittently a force of a magnitude ample to sever the ends of all the strings of fastening-material. The cutting action occurs while the side-rod is rising, and the roll I34 is descending. The reverse movement is an idle one, the projection I36 being pivoted to yield upwardly against a spring I37 but being limited in its downward movement to the position illustrated in Fig. 5. The length of the link I28 may be made variable, as by forming it in threaded sections, to permit the time of action of the roll L34 upon the projection I35 to be adjusted.

The drivers 22, which co-operate with the dieblock-passages 24 and with the passages 35 when these are alined with the latter passages in the forward position of the loader-block for the fastening-inserting operation, are a part of a driverassembly A and are adapted to serve also to prick the work, as a rubber lift, a heel-base and the heel-seat of a shoe in preparation for such insertion. Thus, the elements, which are generally termed drivers throughout the specification, are devices serving a double function and might with equal propriety be called awls. The actuation of the drivers is accomplished in the following manner: Referring to Figs. 1, 5 and 6, there is movable vertically in guides at the front of, the top-girt I8, a driver-slide I50, the weight of which is partially counterbalanced by springs M2, I42 connecting it to the top-girt. Threaded vertically into the under side of the slide is a. screw I44 having its head circumferentially grooved at I45. Extending into the groove is a projection from a carrier-plate I48, and this guides for a horizontal movement of removal and replacement a compound driver-plate I56 having upper and lower sections. The drivers 22 pass through vertical openings in the lower platesection and are held in place by the upper, which bears against their heads. The upper platesection also enters ways in the carrier-plate I48. A spring-latch 552 movable through the driverplate engages a depression in the carrier-plate to lock the former separably in place. Rotation of the screw I44 permits the vertical relation of the drivers to the work tobe altered and therefore the depth to which the fastenings are driven.

Since the drivers must be of a length which will allow them to pass through the die D having considerable thickness, there is best provided near the upper face of said die means for preventing their lateral deflection. This means may consist of a horizontal plate I54 held in place by rods I55, I55 movable vertically through long lugs I57 at the outer corners of the plate I50. The lower ends of the elevated drivers lie in openings I58 in the plate I54, and as they descend during their operation, pass through this and are positively held in alinement with the dieblock-passages 24. The plate is arrested by contact with the die-block, the rods I56 rising through the lugs. It will be seen that the driverplate and the guide-plate furnish a unit which may be removed from the machine by a single act on the part of the operator upon release of the latch I 52. The die-block is also preferably made a part of the same unit to insure the proper change of all these elements when the inserting design is to be altered. To this end, a headed stud I68 projects from the front of the dieblock and has arranged toturn upon it a link I62. This link passes with substantial clearance through an opening in the front of the guideplate and has a retaining nut Iii-i above the plate. As a consequence of this connection, when the die D is freed by the latches E i and the driver-plate I55 and guide-plate I55 by the latch I52, all must be removed and replaced together, and there is no chance that error in the selection of the proper elements will lead to the breaking of the drivers when the machine is started. The loader-block $4, thoughcapable of replacement, preferably contains a multiple design covering all the insertions which are to be made. Consequently, this will properly co-operate with the openings 80 and 24 in any of the die-blocks.

During the pricking operation, the ends of the drivers, or awls, as they are at that time, must pass through the work substantially to the clinching plate of the last within the shoe being operated upon. When the fastenings are being driven, the driver-ends should reach only to points within the heel, as at the outer surface of a layer of reinforcing material which it contains. Therefore, in the portions of the machine-cycle during which the pricking and inserting operations are performed, the ends of the pricking and inserting devices 22 are held at different levels, and this is effected by shifting the block I 40 vertically upon the top-girt. Pivotally connected to the block and to the girt at the front and rear thereof are toggle-levers I75, I79, the upper links of which are shown as joined by a yoke I72 (Fig. 1). The

center of the toggle is united by a link I74 to an upwardly extending arm of a bell-cranklever I76 fulcrumed at the right of the frame Iil. A horizontal arm of the lever is linked at I78 to the slide I04, which, as has been pointed out, is reciprocated through the rod I92 from the camgroove 913 to actuate the loader-block 84 for transferring the fastening-material. When the lever I75 is turned in a clockwise direction, it acts upon the toggle-levers to carry them to the right, somewhat over the center, against a stop-projection I85 upon the top-girt. Since the toggle mechanism is now substantially straight, this lowers the assembly A and positions the drivers 22 at the proper level for the pricking operation.

Opposite movement of the lever I76 shifts the toggle to the left, movement in this direction being limited by engagement of the upper end of the screw I44 with the horizontal wall of the topgirt above it. This elevates the driver-assembly into inserting position. Because the rod I52 must travel for the shearing actuation of the loaderblock by the lever I24 through a greater distance than is necessary for the locatingof the drivers, the movement for breaking the toggle mechanism is transmitted through a spring I 82. To avoid injury to the drivers and tothe last within the shoe being operated upon, if said drivers are carried into contact with the last-plate, springs I86 are interposed between the topegirt and nuts I84 threaded upon the upper extremities of the siderods I2. Consequently, any excess of movement of the drivers will be observed by the springs without breakage of the machine-parts or puncturing of the last-plate.

There may be in the bottoms of some types of shoes, elements through which it is not desired to extend the fastenings. An example of this is found in metal shank-reinforcements which extend back into the heel-seat. We provide for controlling the driver-assembly under such conditions. In the present embodiment of the invention, two drivers I88, I88 (Fig. 6) for the inner breast-fastenings are arranged to prick to a less depth than the companion drivers. These two drivers I88 are carried by a slide I96, movable vertically in ways in the plate I50 but held normally up to an extent determined by the engagement of opposed shoulders i9; upon the slide and plate. This elevation is effected by springs I94 interposed between the slide and a bridge-bar I 96 acrossthe front of the plate. The drivers I88 are shorter than the others, being of such a length that they will not strike the reinforcement in performing their function as awls. When, however, they are to insert the fastenings, their ends should lie in the same horizontal plane as those of the drivers 22, since the outer ends of all the fastenings should bear the same relation to the treadsurface of the heel. To bring this about, there is threaded vertically into the top of the slide I99, a screw 28% lying beneath a contact-bar 292 secured to the top-girt across the outer side of the driver-assembly. The screw is so adjusted that when the toggle-levers I70 are broken for the driving stroke, and the driver-assembly is lifted thereby, the bar 262 is engaged by the screwhead, andthe drivers I88 are held with their lower ends alined horizontally with the drivers 22.

As the basic machine of Patent No. 446,885 is designed, unless steps are taken to prevent it, the clutch 34 would be thrown out after the power-shaft 3!] had turned over once, so the second or inserting portion of the operating cycle would be lost. Moreover, the earns 52, after their first application of pressure to the work, would assume positions in which this pressure would be removed, so, between the halves of the cycle, said work might be displaced, the pricked openings passing out of registration with the dieblock-openings 24. We guard against both these difiiculties. In the outer face of the gear 92 there is a cam-groove 2B6 receiving a roll 2138 upon an arm 2id'fast on the inner end of aspindle 2I2 extending from front to rear of the machine (Figs. 2 and 4) The hub of the arm 2H1 carries a cam-incline 2M, and this, at the end of the first half of the cycle, moves into the path of the clutch-lever 38, retaining this against movement and thus holding the clutch engaged. At the outer or forward extremity of the spindle 2I2 is a short, upwardly projecting retaining arm 2I6. After pressure has been applied to the work in preparation for pricking, the end of this arm is carried under a contact member 2I8 secured to the cross-head 45 of the upper cam 52. This holds the pressure between the halves of the cycle. At the completion of the full cycle, the cam-groove 206 releases both the clutch and pressure mechanisms. e

To increase the holding power of the fastenings, it may be desirable to moisten them prior to their insertion. This activates the adhesive in the material and tends to cause the fastenings to swell. As shown in Fig. 7. a groove or channel 222 is formed in the lower die-block-plate Ill surrounding the tubes IB. This channel is connected by short channels 224 to openings 226, of which there is one through the wall of each tube. The channel 222 is joined by a channel 228 and a pipe 238 to the cylinder 232 of a pump P (Figs.

3 and 9) supported upon the frame above the lever I08 which acts upon the loader-block. The cylinder is supplied with water or other activating liquid through a pipe 234, and in said cylinder a piston 236 is arranged to reciprocate across the port to which delivers the pipe 234 and to ward the port of the pipe 236, which is near the lower extremity of the cylinder. The piston is acted upon by a spring 238 surrounding its rod 24d, this tending-t force it down. It is raised by engagement of the lever I08 with the lower end of the rod and is temporarily held above the port of the pipe 23!) by a spring-actuated latch 242 pivoted upon the cylinder and engaging a collar 244 secured to the cylinder-rod. From a tail of the latch there is a lateral projection 246 extending into a'longitudinal slot in a link 248 articulated to the lever ID8.. When this lever is swung in a contraclockwise direction (Fig, 3), at which time the lever-block 86 is being advanced to sever the fastenings and deliver them to the die-block, a screw 25d, adjustable as to position in the link, strikes the projection 246 and withdraws the latch from beneath the collar. Thereupon, the spring forces down the piston 236 and urges through the pipe 236 the water which has filled the cylinder from the pipe 234. This occurs at a time when the upper ends of the tubes It of the die-block are closed by the drivers. Not having an opportunity to enter freely the tubes which are nearest the delivery-opening of the pipe 239, the charge of water distributes itself along the channels in the die-plate Iii and through the openings 226 into the sections of the die-block-passages which are within the tubes 74, to which are delivered substantially uniform amounts. As the fastenings are advanced by the drivers through the passages, they receive a coating of water which has spread over the inner Walls of the tubes. The quantity of water thus supplied may be varied by changing the downward movement of the piston, as by contact of the collar 244 with the head of a stop-screw 252 threaded into the upper end of the cylinder. When the lever I24 tilts in a clockwise direction, as the loader-block is returned to its fasteningreceiving position, its engagement with the lower extremity of the piston-rod elevates the piston to its normal relation for retention by the latch 242.

The strings of fiber J from which the fastenings are to be formed are supported at opposite sides of the feeder F, upon reels 26% mounted side by side on spindles 232, 262 projecting hori-' zontally from the top of the frame it] (Figs. 3 and 5). Each string passes downwardly from its reel through a passage to receive the action of a feeding pawl 26d and then through a second passage where a retaining detent 255 contacts with it (Figs. 6 and 8). These string-engaging elements may be in form and efiect substantially as is disclosed in Letters Patent of the United States No. 1,849,253, La Chapelle, March 15, 1932, and they will now be described only as to their mounting and actuation. The detents are pivoted in a horizontal series, one for each string, upon a feeder-frame 268, which is mounted at the back of the main frame. With exceptions to be noted later, the pawls are pivoted in a series parallel to the plane of the detents upon a carrier 278, extending at opposite sides of a portion 212 of the feeder frame and arranged to slide vertically thereon. Resting in w a bore in the frame-portion 212 is a spring 274 which at its upper end contacts with an overhanging projection 216 from the pawl-carrier. This spring maintains the carrier and itspawls normally raised to an extent determined by a horizontal arm 218 at the bottom of the carrier, this arm being yielda-bly held by the spring against the frame-portion 272. Upon the rear of the slide I48 included in the driver-assembly A is an arm 288 (Fig. 1), the upper end of which is drawn against one side of the toggle-lever I18 by a spring 282 joining it to the slide. Through the upper portion of the arm is threaded a substantially vertical screw 284. During the pricking stroke of the driver-assembly, the lower end of the screw is vertically alined with the upper face of the carrier-arm 218 (Fig. 5) and, during the later portion of the stroke, contacts with said arm and lowers it against the force of the spring 214. This causesthe descent of the carrier and with it the pawls 264. These grip the strings and advance them into the loader-block 84 to an extent determined by the adjustment of the screw 284. When the carrier rises, under the influence of the spring during the completion of the pricking stroke, the strings are held against retraction by the detents 266. From the detent-passages in the feeder-frame 268, the strings are directed through flexible tubes 288 which terminate in openings through a foot-plate 298. Depending from the foot-plate-openings in registration with the ends of the tubes 238 are the short tubes 82 which enter the openings 88 in the rear portion 18 of the plate 88. In this manner, the strings are continuously guided and are fed to suchdistances into the passages 86 of the loader-block that they will be sheared off in the proper lengths when that block makes its delivering advance. Of course, during the second or inserting stroke of the drivers, the feeder F should be inactive. This is provided for by so arranging the arm 288 that when the toggle breaks, it strikes the upper end of the arm and swings it to the left (Fig. 1) until its screw 284 is removed from above the carrier-arm 218. Consequently, this stroke of the arm 288 under the influence of the driver-assembly is idle. It may be desired to operate the machine, as in connection with the making of adjustments, without causing the feeder to advance the strings. To allow this, the arm 288 has connected to it by a slot-and-screw connection 289 a stop-plate 29!. This may be so adjusted upon the arm, in a direction from front to rear of the machine, that it will either be clear of or will strike the edge of the driverslide I48. Consequently, the arm will either act as just described or will be so retained that it will not engage the arm 218. In the latter case, there will be no feed.

To enable the operator to make readily the change of the die-block D for different inserting designs, the tubes 82 must be lifted from the plate-openings 88 to be reinserted in the new block-openings. This we accomplish without special effort on the part of the operator by making it an incident to the change of the block. The foot-plate has two laterally extending arms 294 (Fig. 1) from the outer ends of which rods 296, 296 project upwardly, these rods being guided at 298, 298 upon the frame. To the right-hand rod is connected a link 388 which,

at its lower extremity, is joined to a crank-pin 382 revoluble by the pivot of the right-hand latch 84 for the die-block. When the latch is turned to release the block, the crank-pin lifts the link and therefore the foot-plate, so the lower ends of the tubes 82 are raised above the plate-portion 18. When the applied block is latched, the tubesdescend to be received by its openings 88. The tubes may be caused to find their way into these openings for all inserting designs, by forming about the upper portions of said openings depressions 384 of generally conical form. The tubes occupy mean positions with respect to the various designs and, by contact of their ends with the walls of the depressions, are guided thereby into registration with the openings.

Reference has already been made to thepricking of certain of the fastening-receiving openings in the work to a less depth than the com.- panion openings so as to avoid striking shankreinforcements. Obviously, the fastenings which are to be inserted in these openings should besimilarly shortened. To bring this about, special mountings are provided for the feeding pawls which act upon the strings from which these fastenings are to be produced. Most clearly appearing in Figs. 6 and 8, these pawls, as those for the two central breast-fastenings, are carried by individual, secondary slides 3l8 movable vertically in the primary slide or carrier 2.18. Each slide is held normally down by a spring 3l2 interposed between it and the primary carrier. Its upper end is vertically alined with a stop-screw 314 threaded through a supporting yoke 3H5 arranged to slide horizontally upon the portion 212 of the feederframe and limited in its travel by screws 328 passing through slots in the yoke threaded into the frame-portion 212 (Fig. 3). Upon idle elevation of the main carrier 218 by the arm 288 in preparation for the feeding stroke, the slides 3H3 contact with the screws 3l4, and their upward travel is arrested before the movement of the main carrier is completed. Consequently, when the'downward feeding travel occurs, the pawls of the secondary slides will have effective feeding engagement with the strings for a shorter time than do the companion pawls, and the lengths of the fastening-material delivered by them to the loader-block will be reduced proportionately. When the two breast-fastenings are to be shorter than the others, as just described, the yoke 3l6 occupies a forward position, so that the screws 3M receive contact of the slides. If no fastenings are to be supplied'by the individual units, the yoke is moved readwardly until the screws are at one side of the slides. In either location, the yoke with its screws may be secured by a spring-plunger 322 movable in the frame portion 212 and entering either of two depressions 324 in the yoke. To supply all the fastenings of the gang of the same length, the screws 3! are backed 01f until the pawls of the slides 3l8 act through the desired length of stroke.

Assuming that the machine is to be utilized for the securing of rubber lifts to heel-bases already attached to shoe-bottoms, the operator will mount a shoe with its base upon the jack 42 and will insert a rubber lift between the spaced arms of a forked plate 338 secured to the under side of the die-block D (Figs. 1 and 5). This plate may have turning about vertical spindles in its opposite arms, rolls 332, 332, the peripheries of which may be knurled to increase their retentive effect. The space between the rolls is such that they slightly indent the rubber to hold the lift securely in place. 7 To avoid mutilation of the lift-wall, when pressure is applied to the work and the lift rises against the die-projection I3, the rolls are permitted to shift longitudinally of their supporting spindles. Consequently, there is no relative movement between the lift and the portion of the retaining means which contacts with and might mar it. The back-stop 4 4 determines the relation of the heel-base upon the jacked shoe to the thus-supported lift. Depression of the treadle 50 will raise the jack by means of the screw mechanism 46 until the lift is pressed against the plate III of the die-block, the guide-projections "I3 entering the lift. The operator then throws down the hand-lever 36, tripping the clutch 34 and initiating a single power-cycle of the machine. The toggle-lever I10 being straightened, the driver-assembly A, with its devices 22 and I88, is so lowered that said devices will pass through the work into the heel-seat of the shoe to perform the pricking operation. During a portion of this movement of the driver-assembly, it causes the arm 280 to lower the carrier 210 of the'feeder l5v with its pawls 264 to deliver fiber strings J from the reels 260 through the tubes 288, openings of the footplate 290, tubes 82 and the rear die'-block-open ings ,80 into the passages 86 in the loader-block 84 to anextent equal to the desired length of the fastenings. The detent's 266 prevent the retraction of the strings. After the pricking has been performed, the driver-assembly rises, and the loader-block is advanced by the lever I08 actuated by the cam-groove 90. In co-operation with the portion 18 of the die-block, the ends of the strings'in the loader-block-passages are sheared off, extra force to accomplish this being applied by the lever I30 joined to the side-rod I2. At the forward extremity of movement of the loaderblock, its passages containing the fastenings are in registration with the die-block-passages 24, and here the loader-block rests While the drivers 22 and I88 make their inserting stroke. The fastenings remain in the block-passages without being displaced by gravity because of the curvature of the cut pieces resulting from the winding of the strings in coils. This curvature causes the fastenings to exert some lateral pressure against the passage-walla Between the pricking and driving halves of the cycle, the clutch 34 is held engaged and the clamping pressure upon the work is maintained under the control of the lever 2H! and the cam-groove 206. In preparation for the driving, the lever I'I6 actuated from the cam groove 90 breaks the toggle III] to lift the lower ends ofthe drivers from the pricking to the driving plane. This toggle-movement swings the feed-arm 280 to an inactive position, so a double delivery of fastenings during a single cycle is prevented. The drivers now perform their second reciprocation and contacting with the fastenings in the loader-block, drive these out through the passages in the plate III into the pricked openings in the work. In their travel ,tom, as a shank-reinforcement, which would be struck by full-length drivers, shorter drivers may bly and changing the Vertical position of the slide under the control of the bar I96. At the same time, the corresponding fastenings may be shortened proportionately by feeding them through the action of the slides 3H], movable independently of the main carrier 210 and governed as to the lengths which they feed by the stationary screws 3I4. If the inserting design is to be altered, the driver-assembly A, the guide-plate- I54 and the die-block D may be changed as a unit because of the connections at I56 and I62. Further, when the die-block-latches 64 are released, the connections 300 simultaneously elevate the foot-plate 290 to separate the tubes 82 from the die-block-openings 88 and thus free said block for removal.
